[0002] Microalgae usually refers to the general term for microorganisms that contain chlorophyll and can perform photosynthesis. They are a type of protists. Microalgae are a type of autotrophic plant that is widely distributed on land and in the ocean. They are rich in nutrients and have high photosynthetic utilization. They produce polysaccharides, proteins, pigments, etc. through cell metabolism, making them have good development prospects in the fields of food, medicine, genetic engineering, liquid fuel, etc. Most breeders will directly discharge livestock and poultry wastewater into the surrounding rivers and canals, which has caused troubles for surrounding residents and also polluted the environment. In order to solve the above problems, people reuse livestock and poultry wastewater to cultivate microalgae, so people start to The livestock and poultry sewage has been treated and applied since its establishment. Therefore, it is necessary to treat the livestock and poultry sewage and filter out the impurities contained in the livestock and poultry sewage. However, when filtering the sewage impurities inside the livestock and poultry sewage, a large number of fine impurities are often filtered out and remain on the filter screen. In this way, the filter screen needs to be replaced regularly, which is cumbersome and inefficient. At the same time, some structures will regularly scrape off impurities through a scraper, but this method will cause fine impurities to fall into the gaps in the filter screen, which is prone to serious blockage.
